Foldable chair

ABSTRACT

The present disclosure is directed to a foldable chair composed of primary and secondary members joined by intermediate members with a hinge-like or pivotal connection formed by passing a wire or cable through opening in the members and anchoring the wire at each end of the joined groups of members. The leg members being interlaced between the intermediate and primary members and the intermediate and secondary members.

FOLDABLE CHAIR An object of the present invention is the provision of alow profile foldable chair which provides a wide radial seat area whenthe chair is erected to a sitting condition and the only pivot joints ofwhich are wire or cable'anchored at each end which permit of modularquick economic construction with a minimum of moving and special parts.

A further object of the present invention is the provision of a foldablechair simple in construction which permits of the use of unskilled laborin its construction as well as blind and retarded people to relieve thestress of unemployment throughout an economically distressed area.

A still further object of the present invention is the provision of afoldable chair for patio or camping use which provides compactness fortransport or storage and which gives a stable low profile comfortablechair.

With the foregoing and other objects in view the invention will be morefully described hereinafter and more particularly pointed out in theappended claims.

In the drawings in which like parts are denoted by reference charactersthroughout the several views:

FIG. 1 is a perspective view of the foldable chair of the presentinvention in its erect sitting condition.

FIG. 2 is a front elevational view of the chair of FIG. 1.

FIG. 3 is a side elevational view of the chair of FIG. 1.

FIG. 4 is a side elevational view of the chair of FIG. 1 in its foldedcondition.

FIG. 5 is a fragmentary side elevational view of the abuttingrelationship between the primary and secondary members caused by theintermediate members.

FIG. 6 is a fragmentary side elevational view of the abuttingrelationship between the rear leg members and the primary andintermediate members.

Referring now to the drawings, the chair of the present inventioncomprises primary members 10 and secondary members 11 which are joinedby intermediate members I2 which are interlaced between the members l0and 11 and joined for a hinged or pivotal connection by a wire or cable13 anchored at each end 14. The cables or wires pass through openingsdrilled in each member. Interlaced with the primary members 10 are twofront legs 15 while two rear legs 16 are interlaced with the secondarymembers 1 1. Both sets of legs are downwardly divergent to providestability and antitip characteristics to the low profile chair as bestseen in FIGS. 1 and 2. The ends of the wires or cables 13 may beanchored by pressed crimp chains or they may be tied or knotted toprohibit separation of the members. The intermediate members 12 not onlyfunction as a joiner between the primary and secondary members but alsoprovide a base spinal support absent from most chairs.

The primary, secondary and intermediate members in the embodimentillustrated are of hardwood but could be also of metal or plastic andcould be of variated interlaced colors to provide pool or patiofurniture readily resistant to swimming pool water.

What I claim is:

l. A foldable chair comprising primary back members joined togetherproximate their top, secondary seat members joined proximate their frontends, intermediate seat members interlaced between said primary andsecondary members and hingedly joined to each member, and leg membersinterlaced with said primary and secondary members and hingedly securedto said intermediate members and extending beyond said primary andsecondary members and being of a length sufficient to support theprimary, secondary and intermediate members above the ground or floor.

2. A foldable chair as claimed in claim I wherein said primary andintermediate members and said intermediate members and secondary membersare hingedly joined by wire means passing through openings in saidmembers and anchored at their ends to hold said members together.

3. A foldable chair as claimed in claim 2 wherein the upright legmembers interlaced between said intermediate members extend beyond thelower hinge joint of said intermediate members and said primary membersand abutt the ends of at least two of the secondary members when thechair is placed in the sitting condition.

4. A foldable chair as claimed in claim 3 wherein the legmembersconnected to said secondary members extend to a point below thetop of the primary members to avoid tipping over of the chair when it isin the erected sitting condition.

5. A foldable chair as claimed in claim 4 wherein the intermediate andsecondary members form the seat of the chair while the primary membersform the back.

1. A foldable chair comprising primary back members joined togetherproximate their top, secondary seat members joined proximate their frontends, intermediate seat members interlaced between said primary andsecondary members and hingedly joined to each member, and leg membersinterlaced with said primary and secondary members and hingedly securedto said intermediate members and extending beyond said primary andsecondary members and being of a length sufficient to support theprimary, secondary and intermediate members above the ground or floor.2. A foldable chair as claimed in claim 1 wherein said primary andintermediate members and said intermediate members and secondary membersare hingedly joined by wire means passing through openings in saidmembers and anchored at their ends to hold said members together.
 3. Afoldable chair as claimed in claim 2 wherein the upright leg membersinterlaced between said intermediate members extend beyond the lowerhinge joint of said intermediate members and said primary members andabutt the ends of at least two of the secondary members when the chairis placed in the sitting condition.
 4. A foldable chair as claimed inclaim 3 wherein the leg members connected to said secondary membersextend to a point below the top of the primary members to avoid tippingover of the chair when it is in the erected sitting condition.
 5. Afoldable chair as claimed in claim 4 wherein the intermediate andsecondary members form the seat of the chair while the primary membersform the back.
